Examples

Example 1: Decimal to Binary Conversion

Input Number (Decimal): 25

Formula: Divide by 2 and record remainders → 25 ÷ 2 = 11001

Result: 11001 (Binary)

Example 2: Binary to Hexadecimal Conversion

Input Number (Binary): 101101

Formula: Group binary into 4-bits → (0010 1101) = 2D

Result: 2D (Hexadecimal)

Example 3: Octal to Decimal Conversion

Input Number (Octal): 157

Formula: (1 × 8²) + (5 × 8¹) + (7 × 8⁰) = 64 + 40 + 7

Result: 111 (Decimal)
